Solution Overview
Problem
The challenge in battery technology is to enhance the space utilization rate of battery cells within a battery's box body, which affects the overall volume and efficiency of electric vehicles, as existing designs occupy excessive space for electrode connections.
Innovation Solution
The solution involves positioning electrode terminals on opposite walls of the battery cell housing in a staggered manner perpendicular to each other, allowing for electrical connections without additional space requirements in the primary direction, thereby optimizing space utilization and reducing the battery's overall volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrode terminals are positioned on opposite walls in a conventional aligned manner, then electrical connection is simplified, but space utilization rate of the battery cell decreases
Solution Approach 1:
The patent applies dimensionality change by transitioning from a conventional aligned arrangement (where both terminals are on the same side) to a staggered arrangement across opposite walls. This spatial reconfiguration utilizes the third dimension (depth) of the battery cell, allowing terminals to be positioned at different locations along the length of the cell while maintaining opposite wall placement. This resolves the contradiction by enabling both simplified electrical connection and improved space utilization through three-dimensional space optimization.
Solution Approach 2:
The patent employs asymmetry by positioning the first electrode terminal and second electrode terminal at different longitudinal positions on their respective opposite walls. Rather than symmetric alignment, the terminals are offset from each other along the length of the battery cell, creating an asymmetric configuration that maximizes space utilization while maintaining electrical connection functionality.
2Volume of moving object
If electrode terminals are positioned in a staggered manner on opposite walls, then space utilization rate improves, but electrical connection complexity increases
Solution Approach 1:
The staggered positioning of electrode terminals on opposite walls utilizes the longitudinal dimension of the battery cell to create an asymmetric arrangement. This dimensional approach allows terminals to be offset from each other along the cell length, maximizing space utilization while the opposite wall configuration naturally facilitates electrical connection through the cell structure.
Solution Approach 2:
The opposite walls of the battery cell housing serve multiple functions: they provide structural containment, enable thermal management surfaces, and facilitate electrical connection pathways. By positioning terminals on opposite walls, the housing structure itself becomes part of the electrical connection system, reducing the need for additional complex external connection components.

AI summary
Provided are a battery cell, a battery, a power consumption apparatus, a method and an apparatus for preparing a battery. A battery cell includes a housing, including a first wall and a second wall oppositely provided in a first direction; two electrode terminals, respectively located on the first wall and the second wall, where projections of the two electrode terminals on a plane perpendicular to the first direction are staggered from each other. Through the technical solution, when the electrode terminal is electrically connected with other electrical components, other electrical components may be provided side by side with the electrode terminal by using space perpendicular to the first direction, and other electrical components do not need to occupy additional space in the first direction, thereby saving space required to achieve an electrical connection of the battery cell, and increasing a space utilization rate of the battery cell in the battery.
